Primary Frequency Control in the Power System of Continental Europe including the Dynamics of the HVDC Link France-Great Britain

2020

The paper presents a study of primary frequency control within the power system of Continental Europe (CE) including the dynamics of the high voltage direct current (HVDC) link between France and Great Britain (GB). The large-scale dynamic model of the CE system originally provided by ENTSO-E is extended with a more detailed representation of the whole HVDC interconnection. The dynamics of the GB synchronous area is also considered in the analysis, implementing a system equivalent suitable for primary frequency control studies. The opportunity of frequency containment reserve exchange between the two areas through the link is also investigated, considering supplementary frequency controls w…

Hysteresis Model of Unconscious-Conscious Interconnection: Exploring Dynamics on m-Adic Trees

2015

The theoretical model outlined in this paper, has been experimentally validated by: H. Kim ,J-Y. Moon ,G.A. Mashour & U. Lee, ''Mechanisms of hysteresis in human brain networks during transitions of consciousness and unconsciousness: Theoretical principles and empirical evidence'', PLOS-Computational Biology, August 30, 2018, https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1006424; International audience; In this brief note, we focus attention on a possible implementation of a basic hysteretic pattern (the Preisach one), suitably generalized, into a formal model of unconscious-conscious interconnection and based on representation of mental entities by m-adic numbers. …

REDES Y (CIBER)FEMINISMOS. La revolución de la representación que derivó en alianza

2018

Propongo reflexionar sobre cómo los énfasis ciberfeministas han ido cambiando en las últimas décadas paralelamente a las transformaciones sociales derivadas de la construcción de un mundo en red. Valorando que hoy los mayores logros y movilizaciones no han venido de las “formas de representación” poscuerpo como sugería el primer ciberfeminismo, sino de la potencia de la alianza feminista en Internet. Para indagar en este escenario reciente, sugiero cinco puntos de entrada al ciberfeminismo y sus lecturas sobre representación y alianza destacando en todos ellos la influencia que el activismo artístico ha tenido. Comenzaré situando algunos “modos de hacer” que caracterizaron la primera época.…

An Online Inquiry Tool to Support the Exploration of Controversial Issues on the Internet

2016

This paper describes a theoretically informed Online Inquiry Tool designed to support the exploration of controversial issues on the Internet. The tool’s design is grounded in principles associated with theories of online research and comprehension, argumentation for learning, representational guidance, and cognitive load. The purpose of the tool is to help students organize, monitor, and regulate several complex cognitive activities likely to present challenges during online inquiry. Supports are embedded into the digital tool to help students plan their information search around a controversial issue, identify supporting arguments and counterarguments related to this issue, critically eva…

Virtual Space and the Contention over Representations of the City

2015

The European Capital of Culture (ECOC) is one of the longest running cultural initiatives of the European Union (EU). The EU annually designates one or more cities with this much-competed-for city brand. In various cities the ECOC designation has caused tensions and disagreements over the decision-making process, funding of cultural events, and the use of urban space. These disputes have also generated urban activism that uses various platforms to contest ECOC policies: public discussions in the local media, Internet sites and blogs, as well as alternative events and activities organised by the citizens themselves. This chapter investigates the conflict related to the ECOC designation of Tu…

Rough Pragmatic Description Logic

2013

In this chapter, a rough description logic is built on the basis of a pragmatic standpoint of representation of knowledge. The pragmatic standpoint has influenced the acceptance of a broader definition of the semantic network than that appearing in the literature. The definition of the semantic network is a motivation of the introduced semantics of the language of the descriptive logic. First, the theoretical framework of representation of knowledge that was proposed in the papers [24,25] is adjusted to the description of data processing. The pragmatic system of knowledge representation is determined, as well as situations of semantic adequacy and semantic inadequacy for represented knowled…

Variations on Weyl's theorem

2006

AbstractIn this note we study the property (w), a variant of Weyl's theorem introduced by Rakočević, by means of the localized single-valued extension property (SVEP). We establish for a bounded linear operator defined on a Banach space several sufficient and necessary conditions for which property (w) holds. We also relate this property with Weyl's theorem and with another variant of it, a-Weyl's theorem. We show that Weyl's theorem, a-Weyl's theorem and property (w) for T (respectively T*) coincide whenever T* (respectively T) satisfies SVEP. As a consequence of these results, we obtain that several classes of commonly considered operators have property (w).

Representations of individuals in discourses oflaïcitéfromLe Monde: confirming or challenging the republican framework of identity?

2016

ABSTRACTIn recent decades, the notions of laicite and identity have been subjects of controversy in France. The two concepts have become sufficiently co-associated since the 1990s to ensure each almost systematically entails the other. Findings from previous studies have pointed out harmful implications of this pervasive association for minorities in France, especially Muslims. This study examines further the ways laicite and identity are interwoven by exploring who is represented (and how) in newspaper articles from Le Monde dealing with laicite. Informed by critical intercultural communication scholarship, intersectionality, and a Foucaultian approach to discourse, this study pays particu…

INTIMATE PARTNER VIOLENCE: PERCEPTION AND REPRESENTATION OF VIOLENCE AGAINST WOMEN IN GUANAJUATO. A QUALITATIVE RESEARCH

Intimate partner violence and domestic violence refer to the violation of women’s rights, often provoked by socio-cultural norms based on a patriarchal matrix. In Mexican society, in particular, gender-based violence affects the physical and psychological well-being of Mexican women. Moreover, the social representations of women who suffer violence and the lack of an effective legislative framework often reproduce the legitimation of gender-based violence, enhancing negative stereotypes and prejudices. In this scenario, the voice of the women who suffer violence in intimate relationships is silenced. In particular, in public and academic debates the impact and consequences of violence again…

Il mare colore del sangue

2018

In their artwork "Calendoola: SURUS", visual artists Simone Trabucchi and Simone Bertuzzi AKA Invernomuto, in their characteristically visionary language combine sensory experiences and political urgency, offering a reflection on a potentially dystopian society incapable of coming to terms with its own history of colonial, imperial, neocolonial, and global domination. In their 2018 installation at the MAXXI Musuem in Rome, men bleed, turtles lie on their backs, and elephants look on, wise and inexorable. Meanwhile the sea is burning and has turned blood-red. It is the blood of the sons who cross it from opposite sides of the Mediterranean, some succeeding, others succumbing to its abysses. …
